invalidateLater

Approximate milliseconds to wait before
  invalidating the current reactive context.

millis

Schedules the current reactive context to be invalidated
  in the given number of milliseconds.

Shiny makes it incredibly easy to build interactive web
        applications with R. Automatic "reactive" binding between
        inputs and outputs and extensive pre-built widgets make it
        possible to build beautiful, responsive, and powerful
        applications with minimal effort.
